How the animals found their places : pattern detection, experimentation, and epistemology in a high desert stream fish assemblage

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...

Ecological relation of sympatric steelhead and resident rainbow trout in the Deschutes River, Oregon

Creator:: Zimmerman, Christian E.
Abstract:: Sympatric steelhead and resident rainbow trout (Oncorhynchus mykiss) are known to exist in many rivers throughout the Pacific Rim. Whether sympatric steelhead and resident rainbow trout are polymorphisms within a single gene pool or two reproductively isolated populations has significant implications concerning the study and conservation of this polytypic species....

Rearing density as a driver of adaptation to captivity and traits under selection by domestication in hatchery reared steelhead (Oncorhynchus mykiss)

Creator:: Thompson, Neil F.
Abstract:: Releasing hatchery reared salmon and steelhead to supplement threatened and endangered populations is a widely used conservation tool. One issue with this strategy is hatchery fish have lower reproductive fitness than wild fish when spawning in the wild. One of the drivers of fitness loss in steelhead is adaptation to...

Estimated expenditures by sport anglers and net economic values of salmon and steelhead for specified fisheries in the Pacific Northwest

Born to run? Integrating individual behavior, physiology, and life histories in partially migratory steelhead and rainbow trout (Oncorhynchus mykiss)

Creator:: Sloat, Matthew R.
Abstract:: Steelhead and rainbow trout are common names for marine-migratory (anadromous) and freshwater-resident forms of Oncorhynchus mykiss, a partially migratory salmonid fish. Anadromous and resident forms are sympatric and can produce offspring with a life history different from their own (i.e., steelhead parents can produce rainbow trout offspring and vice versa)....

The Pacific Coho salmon fishery : an intraseasonal and interregional economic analysis of the ex-vessel market

Creator:: Swartz, A. Nelson
Abstract:: The ex-vessel coho salmon market has been paid scant attention in the study of the salmon resources. This study is an attempt to advance an understanding of the variations of ex-vessel prices and landings during the coho season as well as between the various coastal ports where the fish is...

Impacts of multispecies parasitism on coho salmon (Oncorhynchus kisutch) in Oregon

Creator:: Ferguson, Jayde A.
Abstract:: Diseases caused by parasites are recognized as significant sources of mortality in wild fish populations. I assessed the impacts of multispecies parasitism on a threatened stock of juvenile coho salmon (Oncorhynchus kisutch). A crucial prerequisite to this research was proper identification of parasites, which can be difficult for species lacking...

Salt marsh reestablishment following dike breaching in the Salmon River estuary, Oregon

Creator:: Mitchell, Diane Lynne
Abstract:: A 22 ha, 1S yeas old, diked permanent pasture in the Salmon River estuary in Lincoln County, Oregon, was chosen for a study to determine the potential for natural salt marsh restoration with dike breaching. Two undiked fragments of relatively undisturbed salt marsh, one at each end of the study...

Applying random utility modeling to recreational fishing in Oregon : effects of forest management alternatives on steelhead production in the Elk River watershed

Creator:: Alexander, Susan J.
Abstract:: A random utility model of trip demand for steelhead fishing is constructed by using a logit regression technique and data from the 1990 Oregon Angler Survey, conducted by the Oregon Department of Fish and Wildlife. The model is formulated to estimate demand when only the regional destination is known. Results...

Cumulative effects of land use on salmon habitat in southwest Oregon coastal streams

Creator:: Frissell, Christopher Andrew, 1960-
Abstract:: As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which...
